I decided to change the keyboard shortcut for "Save for Web & Devices" to Command-Option-S but I noticed that it was already assigned to "Save As". So I look over and also notice "Save As" has 2 shortcuts assigned to it. I'm just curious why this is the case by default? In this case, was Command-Option-S a legacy shortcut for "Save As" on older Macs or something?

Also, why do shortcuts always require Command? I'd wanna reduce the number of shorcuts that require 4 keys by utilizing Control or Option.

Lastly, with the first issue above, just wanted to point out a minor error in the copy that says "File > File > Save As" when referring to the "Save As" path.

As I've said numerous times, we're not here to explain Adobe or Apple, nor to apologize for either of the two corporations. It's very unlikely that Adobe staff who drop by as volunteers, on their own time and dime, will respond to this type of questions.

It's futile to ask why. It just
is.

As for the double "File >" entry, you would need to submit a formal bug report through the Contact button at the top of this page.

Also, why do shortcuts always require Command?" - They don't, here's a workaround for this available since Photoshop 5 - you can use Actions - record an action step "Insert Menu Item here". Choose your menu item, then you can use a single F keys for any menu command. No-one apart from me, and one mystery person at Adobe ever seemed to know this existed until now.

"Save as" has two shortcuts because different software used a different shortcut for this - the Adobe standard shortcut is Command/Shift/S

Ramon, that's a ridiculous stance to take on a user-to-user forum. When I ask a question or raise a concern, it's really to pull from the vast experience of the Photoshop community, not necessarily from Adobe devs (although I do appreciate their replies in one of my recent posts). I bring it up simply because it's a discussion point and perhaps others are willing to provide their opinions or have knowledge of some facts.

Mark, sorry but I should've included the function keys in that sentence. What I was really trying to get at was being able to use shortcuts that make use of the Option or Control keys, like Option-S, Control-Z, Option-Shift-S, etc.

Thanks Chris and Ann, I went back and read
Apple's UI guidelines and it gave me a little better understanding of their keyboard shortcut standards. For example, I noticed the lack of shortcuts in Photoshop which made use of the Control key, but this may be partially explained by this guideline:

Because the Control key is already used by some of the universal access features as well as in Cocoa text fields where Emacs-style key bindings are often used, it should be used as a modifier key only when necessary.

Also, I imagine Adobe may want to keep similar shortcuts across multiple platforms and since Command and Control are swapped between Windows and Mac, you may not want to use that combination since there's no equivalent for both on the PC. (Just thinking outloud, I might be completely off here.)

My work around is to use ControllerMate to cause one keypress to simulate another.

There is more to it under the hood, but the simple version is: menu shortcuts require the command key because that's the way menus work on Macintosh.

Hold on! Is that a Carbon thing?!

There are certainly lots of applications that allow menu shortcuts without command. It's even possible to specify shortcuts without command using the OS X Prefs panel, though that doesn't seem to work for Photoshop, either.
